This "invention relatesto systems and consists' in certain' improvements in the constructionntherecf aswill be hereinafter full describedandzpointed out'in the claims. ore i particularly 'the' invention relates to thesellightihgiunits whichinvolve the use of :an explosive engine and-hasior its object the simplifying offsuch mechanisms and rendering the same more 'nearlyiautomatic in their operation I i *The mantis is illustrated in the atompanying drawings 'whereim 1-=inarks the explosiveengine,-2 allighting generator, 3 a charging: generator 'an d starting motor, 4 a

' magnetouforthe engine, 5 a storage battery and. 611i; light *The' magneto may be ;dispensed with-and the ignition accomplished either-Z fromthe' storage battery or a separate supply and the charging generator and start ring motor '3 maybe formed in: separateunits or.may-be combined.

-Withthe lighting systems of common use it'is' the usual practice to charge the battery' andmse the current directly from the battery.-or iii-connection with that going to engine. Another system is the battery and where a high voltage system is used this requires a very large and expensive battery. On the other hand, it does not require the constantrunning of the to permit the engine-to run continuously. With this system a very small battery, if any, is required. With the present'system it is proposed to use a small battery simply large enough f'or opcrating the starting motor preferably at low voltage and to automatically start the engine at any time a switch is turned on and a light. In carrying out the system as soon as the switch is turned on, the ignition system is connected up, the engine is started, the lighting circuit connected, the starting circuit disconnected and the charging circuit connected so that as the engine runs the storage battery is charged. On opening the switch at the light the ignition system is opened stopping the engine and the connection to the storage battery is opened.

The light 6 is between the wires 7 and 8.

The wire 8 has'the'switch 9 ordinarily the socket switch by which the li'ght is turned on and ofi'. The wire 8' runs to a coil 10 and from the coil'lOby a wirell, wire 12 =to a coil 13, from thecoil :13 by the wire 14 tothe switch: 15; thencebyrwires 16-and l7' to'the battery 5. It will be readilygseenthat asi the switch 9 is closed;'currenti.-fromtheibit terv 5 will flow through the coils 10 and 13.

The coil 10 operating-on the 'p1ate18 over- Patented 9, i

comes the spring 19 which normally holds:

the plate outwardly as i to" close a connection between the wires 20-:and =21. 1 The etc-'4? wires 20 and 21 leadsto' the ina As soonas the switchi-formcdby t el'platel 18 is opened, the magneto circuit leads-to the ground 23 at one side and byway of the wire 24 which connects'with the wire 21 J engine forming aground at the other side to the spark plug 25=at=the otherside of the of the circuit so that the igi1itioriflsystem is a connected up; The1'coil413 5 attracts-Aha plate 26 and overcoming the" spring 27 'c loscs' a switch in the wire 28. The: wire 28 lcads -i to a wire 28* andthe wire 28* to one side of the starting motor by'way of the' wires 29-- and 1:7 to the storage battery. The opposite side ofit-hestarting motor 3 is oonhectedby way of the wire 30 with the wire 7 leading to the storage battery. Thus as soon as the switch 9 is closed and current; supplied to the (oil 13 the circuit between the battery and the starting motoris closed thus starting the engine. -As soon as the engine starts, cur want is developed inthe lighting generator'2. A wire 31 leads from one side of this generator to the wire ll-and thence tothe wire8 as heretofore traced. The opposite side of the generator leads through the wire 32, wire 33, coil 34 and wire 35 back to the wire 31 forming a circuit through the coil 34. As soon as the current is sufiiciently developed to overcome the spring 34*, the switch lever 36 is movedyopeningrthe switch 15 and closing the switch 37. he switch 37 closes a connection between the wire 32 and the wire 7 so that there is a lighting circuit by way of the wires 31, 11, 8, 7 and 32. There is sufiicient resistance in the coil 34 to prevent an undue amount of current passing throu h this coil. At the same time, there is SlIillClBllt while the lighting generator is in operation to hold the lever 36 in position to close the switch 37.

The opening of the switch 15 breaks the circuit through the coil 13 and the switch Elate 2h is retracted by the spring 27 thus reaking the circuit between the storage battery and tha -starting motor; The movement of the switch lever 36 closes a switch 39. A wire 40 leads to the wire 28 and tb us to Qneside of the starting motor and chargiiig"gli'irabbr 33 The wire"38 leads from the other side oi; the switch- 39 tovthe' wire 29 and thence by the wires 29 and 17 to the storage battery. The'goonnection with the generated 3" is-gr'etain'ed through the wires 30' and 7 to= .=thestorage battery; Thus during the runnings of the engine-and a-fber' currentis in' the lighting circuit, connection isqmade' ,whereby the; generator -3 charges the battery." ;It.'-willsboiiriderstood that: the
